I will never feel morally comfortable about an economic arrangement where I get to consume the fruits of many laborers for comparatively little work myself. Although, we've been taught that this is the American dream and indeed it is the American reality. The USA is 5% of the population of the world, but it consumes 25% of the economic output. We can't all feed disproportionately on each others' labor, it's mathematically impossible.

There are better studies that link the extremely wealthy to sociopaths. There's absolutely no doubt that on the whole they have absolutely no empathy for the destitute and poor. Welcome to America, right?

The more wealth you have the more interested (and wrapped up) you become in protecting it. Protecting your interests and compassion are anathema.

One of the things about growing wealth is that a large part of how to do that involves protecting what you've already got. It's a part of an (almost) all-consuming mindset for wealth. You need to take risks, and that means considering all the things that would threaten your investment, enterprise, etc.

You could tell a wealthy person that they could be more compassionate and thus greatly reduce those desperate enough to rob them (or whatnot), but they are used to considering far more short-term, quantifiable ways of protecting their wealth.
